[WTB] Wizard OH Source (300dmg, +INT, +Crit)

I'm looking for a Demi-Lich off-hand source with a top max damage over 300, +Intelligence of at least 70 (or lower if it has a socket) and a crit chance of 8%. I don't care about any stats other than these.

I'm broke and am struggling to even make a consistent profit right now farming Act I, but this is the one item that I think I can upgrade and make a major difference in my game most effectively. I currently have 620k to my name, and hopefully I won't lose much of that to repair costs tonight.

Please help. Thanks.
